3. PW3337 Power Meter

The PW3337 is a precision power meter with three input channels. It supports DC, single-phase two-wire, and three-phase four-wire measurements.

Its specified basic measurement accuracy is ±0.1% under applicable conditions, and its frequency measurement range extends from DC to 100 kHz. With suitable current sensors, it can also support measurements beyond its direct current input range.

The PW3337 is useful for industrial testing, power supply evaluation, and electrical equipment development.

4. PW3336 Power Meter

The PW3336 provides two input channels for electrical power measurement. It supports DC and several AC wiring configurations, including single-phase two-wire and three-phase three-wire systems.

This model can be considered for applications involving power supplies, inverters, and industrial electrical equipment. The appropriate choice depends on the number of measurement points and the required circuit configuration.

Main Applications of HIOKI Power Analyzers

Motor and Inverter Efficiency Testing

Motor and inverter testing helps engineers understand energy conversion performance and identify potential losses. By measuring electrical input and output power, engineers can evaluate the efficiency of a power conversion system.

HIOKI power analyzers support these measurements when configured for the relevant electrical system. Mechanical output measurements may require additional compatible instruments or sensors.

Electric Vehicle and Power Electronics Testing

Electric vehicle development involves testing inverters, charging equipment, and other power conversion components. High-precision electrical measurements help engineers investigate performance under different operating conditions.

Advanced analyzers can also support the evaluation of switching power devices, including silicon carbide (SiC) and gallium nitride (GaN) technologies.

Renewable Energy Systems

Solar inverters convert DC electricity into AC power. Measuring the input and output power helps engineers evaluate conversion efficiency and compare performance under different operating conditions.

HIOKI power analyzers can support these applications when their measurement ranges, bandwidth, and accessories match the test requirements.

Power Supply and Industrial Equipment Testing

Manufacturers use power meters to evaluate the electrical performance of power supplies, appliances, and industrial equipment. These measurements can support product development, quality control, and production testing.

Depending on the instrument, engineers may also analyze harmonics and other electrical parameters to investigate power quality and equipment performance.

How to Choose the Right HIOKI Power Analyzer

Selecting the correct instrument requires careful evaluation of the application and measurement conditions.

Measurement accuracy: Check the complete accuracy specifications, including applicable voltage and current ranges, sensor errors, and environmental conditions.

Voltage and current ranges: Ensure the instrument and accessories support the maximum expected electrical values. High-voltage and high-current applications may require compatible external sensors or voltage accessories.

Frequency bandwidth: Select a bandwidth appropriate for the signal characteristics and switching frequencies involved in the test.

Number of channels: Consider whether you need single-phase, three-phase, or simultaneous input/output measurements.

Analysis functions: Determine whether harmonic analysis, waveform evaluation, motor-related functions, or synchronized data acquisition are necessary.

Connectivity: Check the available communication interfaces and software compatibility if you plan to integrate the instrument into an automated testing system.

Power Meter vs. Power Analyzer

A power meter is generally used to measure electrical power and related parameters, while a power analyzer often provides additional functions for detailed electrical evaluation.

However, the distinction depends on the model. Some power meters offer advanced measurement functions, and power analyzer capabilities vary by configuration.

For routine power consumption testing, a suitable power meter may be sufficient. For complex inverter testing, motor development, and high-frequency power electronics research, an advanced analyzer may provide more appropriate measurement capabilities.
